-Subject: [PATCH] wifi: rtw88: schedule rx work after everything is set up
-Date: Tue, 28 May 2024 13:02:46 +0200
-
-Right now it's possible to hit NULL pointer dereference in
-rtw_rx_fill_rx_status on hw object and/or its fields because
-initialization routine can start getting USB replies before
-rtw_dev is fully setup.
-
-The stack trace looks like this:
-
-rtw_rx_fill_rx_status
-rtw8821c_query_rx_desc
-rtw_usb_rx_handler
-...
-queue_work
-rtw_usb_read_port_complete
-...
-usb_submit_urb
-rtw_usb_rx_resubmit
-rtw_usb_init_rx
-rtw_usb_probe
-
-So while we do the async stuff rtw_usb_probe continues and calls
-rtw_register_hw, which does all kinds of initialization (e.g.
-via ieee80211_register_hw) that rtw_rx_fill_rx_status relies on.
-
-Fix this by moving the first usb_submit_urb after everything
-is set up.
-
-For me, this bug manifested as:
-[    8.893177] rtw_8821cu 1-1:1.2: band wrong, packet dropped
-[    8.910904] rtw_8821cu 1-1:1.2: hw->conf.chandef.chan NULL in rtw_rx_fill_rx_status
-because I'm using Larry's backport of rtw88 driver with the NULL
-checks in rtw_rx_fill_rx_status.
